Usage Explanation

The fields and environmental variables are given as arguments to the program and the non-null ones are e-mailed to the recipients in a particular format. If none are given as arguments, then a whitespace-separated list of arguments are taken from the "_mail_vals" field.

If no recipients are given as arguments, then the field "_mailto" is interpreted as a whitespace-separated list of e-mail recipients. If "no one" is the first (or only) recipient, then no mail is sent.
